RADIATOR CON CON Dec. 7, 1954 United States Patent 0 RADIATORCGNSTRUCTION FOR USE IN CONVECTOR HEATING SYSTEMS Ray C. Edwards,Pompton Plains, N. J. Application February 3,'1953,'Serial No. 334,874 5Claims. (Cl. 257-133) This. invention relatesv to space heating systemsfor heating rooms or analogous enclosures, and more particularly to thattype of heating system known in the .art as baseboard convectors whereinheat exchange means such as finned tubes are arranged along a wall orwalls of an enclosure substantially at baseboard level,

above the floor, and a heating medium such as hot water or steam iscirculated through the heat exchange means to heat the enclosure.

A principal disadvantage to heating systems of the baseboard convectortype now in use and employing finned tubes is that in installing theunits around a'room or enclosure. the finned tube elements andcompanionable connections and piping must be assembled -on the oor ofthe room prior to placing them in position on their supports in theenclosing structure. This is a cumbersome operation as the assembly oftubes and connections areL of the room and subsequently placingk theassembled,`

unit upon its supports.

In heating apparatus of this type now in use, the finned tubing is sosupported that longitudinal movement thereof or of sections thereof isprevented. Such movement is caused by expansion when the heating mediumis rst circulated through the tubes after it has been turned off, or thecontraction of the tube during cooling after the circulation of theheating medium has been turned l, off, and thus such expansion orcontraction causes undesirable nolses due to abrasive action orspringing of the tubes and supports.

Another advantage of the present invention, is the employment of a noveltype of support for the finned tubes whichwill permit unimpeded movementof the tubes relative to the supporting enclosures and thus eliminatesuch undesirable nolses.

A further advantage ofthe present invention is that the supports of thepresent invention may be employed with either round finned elements orwith those wherein the tins are lipped as shown in my prior Patent No.2,529,545, issued November 14,v 1950, andv that irrespective of the typeof tube elements employed, they will be always centered with respect tothe front and back of the enclosing enclosure or casing of the heatingunit.

Another object of the present invention is the provision of a novel,simple and inexpensively yconstructed damper and means for operatingitwhereby the cross sectional area of the heated air outlet of theconvection heating unit may be regulated. Y

With these and other objects in view, as may appear from theaccompanying specification, the invention consists of various featuresof construction and combination of parts, which will be tirst describedin connection with the accompanying drawings, showing a radiatorconstruction for use in convector heating system of a preferred `formembodying the invention, and the featuresforming the invention will bespecifically pointed out inthe claims.

r t 2,696,358 Ice Patented Dec. 7, 1954 In the drawings:

Figure l is a fragmentary front elevation of the rad1ator for use inconvector heating systems.

Figure 2 is an end view of the radiator.

Figure 3 is an enlarged detail section taken on the line 3-3 of Figure2.

Figure 4 is a fragmentary detail perspective view of a part of theradiator. y

Figure 5 is a fragmentary detail perspective view showing the damper andits operating mechanism.

Referring more particularly to the drawings, A indicates a fragment of awall of a room or enclosure and B indicates the oor thereof. Thebaseboard convector heating device or radiator is placed along any oneor more of the walls A of the enclosure as desired, substantially atbaseboard level, that is, at a level on the wall A .which is normallyoccupied by the baseboard (not shown).

The heating unit or radiator includes a shallow casing including abackplate 1 attached to the wall A by suitable means such as screws 2.The upper edge portion of the backplate 1 is curved outwardly as shownat 3 to provide a heated air directing portion for directing the heatedair into the enclosure. From the upper outer terminus of the curvedportion 3 the backplate angles upwardly and inwardly as shown at 4 andfrom thence back to the wall A where it is bent to provide the attachingflange 5. The flange 5 is attached to the wall A by the material C usedto form the interiorinish of the wall A or by any other suitable means.

t An angled supporting plate 6 is attached to the backf plate 1V at ornear the rear lower terminal of the curved portion 3, and while only oneof these angled supporting plates are shown in the drawings it is to beunderstood that any desired or required number of them may be provided,being spaced at suitable intervals along the length of the backplate 1.

The angled supporting plate 6 extends outwardly and upwardly from thebackplate 1 as clearly shown in Figure 2 of the drawings and has a sharppointed upwardly extending tongue 7 formed on its upper outer cornerwhich engages in and beneath the upper rolled edge 8 of the frontplate 9to removably support the upper edge portion of thelfrontplate 9 inproper spaced relation to the backp ate An adjustable support plate 10is provided which has a slot 11 cut therein near its upper end by meansof which it is adjustably connected to the backplate 1 by means of oneof the screws 2. While only one adjustable supportplate 10 is shown inthe drawings it is to be understood that any desired or required numberof these plates may be provided, depending upon the length of theradiator. e

A pin or shaft-12 is carried by the adjustable supporting plate 10 andextends horizontally outward therefrom to the frontplate 9. A roller 13is rotatably mounted upon the pin 12 and is held against longitudinalmovement thereon by any suitable means such as pins y14. The roller 13has a concave perimeter the curvature of which is designed or cut toapproximately conform to .the curvature of the perimeter of the ns 15'on the finned tube 16'- through which the heating medium such as hotwater or steam is circulated. i

The linned tube 16 may be of the conventional nned tube construction orit preferably is of the lipped tin type such as shown in my prior PatentNo. 2,529,545 issued November 14,' 1950, and resting upon the concavesurface of the rotatable roller 13, it may be moved longitudinally withease to permit'attachment of the connections or connectors (not shown)at the corners of the enclosure when assembling the system, and also itmay move' on or with the rotating rollers under expansion or contractiondue to heat variances after' the assembly has been completed and duringuse.

The provision of the rotatable rollers as support for the iinned tubepermits greatly 'simplified operation of construction or assembly of thesystem in an enclosure as hereinbefore referred to and eliminatesundesirable noises during operation of the system also as hereinabove SOreferred to.

The lower edge of the frontplate 9 is also rolled as shown at and novelmeans are provided for holding this lower edge in position.

A Cotter-pin type spring element or member 16 is inserted diametricallythrough the pin 12 and its legs 17 are spread and curved outwardly and'downwardly and engage between the upper inner terminus of the rollededge l5 and the adjacent inner surface of the frontplate `as clearlyshown in Figures 2 and 3 of the drawings to releasably hold the lower'portion of the frontplate 9 in position.

The angled support plate or bracket 6 has its attaching end 18 by meansof which it s attached to the backplate 1 Wider than the width of thebracket 6 to form a tongue or extensionl and this tonguev 19 is rolledas clearly shown in Figures 4 and 5 of the drawings, to form one sectionof a hinge, which cooperates with the hinge' section forming rolledinner edge 20 of a damper 21. The interconnecting of the hinge sections19 and 20 or swingably connect the damper 21 tol the bracket 6 and theback-plate 1. The damper 2'1 extends across the space between thebackplate 1 and frontplate 9 from the lower terminal of the curvedportion 3 and the upper rolled edge 8 and by adjusting the position ofthe damper 21 the cross-sectional area of the outlet space for theheated air into the enclosure may be regulated as desired.

A simple, inexpensive, and practical device is provided for adjustingthe position of the damper 21`.

This device comprises a support 22 attached to the frontplate 9 andextending beyond its upper edge. A pin 23 is rotatably carried by thesupport 22 and has its inner end attached to an angled damper operatingmember 24 the angled end 2S of which engages the damper 21 so that whenthel pin 23 is rotated the damper 21 will be moved. facilitate itsmanual rotation, and a spring 27 is coiled about the pin 23 between thefrontplate 9 and the member 24 to hold the damper in adjusted positionsby the pressure of the spring against the operating member 24.

If it is so desired a laterally extending damper supporting extension 28may be formed upon the upper edge of the bracket or angular supportingplate 6, but this supporting extension 28 may be eliminated withoutdeparting from the spirit of the invention.

It will be understood that the invention is not to be limited to thespecific construction or arrangement of parts shown, but that they maybe widely modified within the invention defined by the claims.
